I was talking with a Revit user the other day that was having trouble placing a Truss object in their Revit Structure. After they placed the truss, it would disappear even though all visibility settings for the view were correct in allowing it to display. Needless to say, the user was frustrated. The problem was that there were no members defined for the truss, so only the truss’s reference lines were visible when the truss was highlighted.
